18. T. anthoeliroa, P . ; effused, subadnate; circumference
byssoid, paler; Lymenium even, brownish-rose, at length pallid,
floccose and velvety.
Var. versicolor.
On sycamore twigs. Rare. Wothorpe. My plant, when
dry, resembles authentic specimens from Pries, but when fresh
is variously tinted with fugitive shades of lilac and brown.
36. STEREUM, Fr.
Hymenium coriaceous, rather thick, concrete with the intermediate
stratum of the pileus, which has a cuticle, always
even and veinless, unchangeable, not beset with bristles.
1. S. purpurenm, P r .; soft, hut coriaceous; pileus effuso-
reflexed, obsoletely zoned, villoso-tomentose, pallid or dirty-
white; hymenium naked, even, smooth, purplish or lilac.—
Soiv. t. 388. /. 1; Huss. i. t. 20.
On trunks of fallen trees, especially poplars. Extremely
common, and often very beautiful. Auricularia elegans, Sow.
t. 412. f. 1, is merely a state of this.
2. S. hirsutum, Fr.; coriaceous; pileus effused and reflexed,
strigoso-hirsute, somewhat zoned, turning pallid; margin
rather obtuse, yellow; hymenium even, smooth, naked, juiceless,
bright tawny-yellow, unchanged when bruised. (Plate
17, fig. 7.)—Huss. i. t. 58.
On stumps of trees, etc. Everywhere. Found also in subtropical
countries.
3. S. spadiceum, F r .; coriaceous; pilei effuso-reflexed, villous,
subferruginous; margin rather obtuse, white, even beneath,
smooth, brownish, when fresh bleeding if bruised.__
Sow. t. 28.
On sticks, especially oak. Common. Often very pretty;
variable in colour, but easily distinguished from every species
except S. rugosum and the following, which is confined to
Conifers, by its turning red when scratched or bruised.
4. S. sanguinolentum, Fr. ; thin, coriaceous ; pileus effused
and reflexed, silky, somewhat striate, pallid; margin acute,
white; hymenium even, smooth, cinereous-brown, bleeding
when wounded.—Grev. t. 225.
On wood of Conifers. Very common. Colour far less bright
than that of the last. A. hepática. Sow. t. 388. f. 2, is
merely a washed state of one of the foregoing species, probably
S. purpurenm.
5. S. rugosum, Fr. ; corky, rigid ; pileus effused and shortly
reflexed, obtusely margined, at length smooth, bright brown ;
hymenium dull, pruinose, bloodstained when wounded.
On stumps, especially hazel. Extremely common. Sometimes
surviving one or more seasons, and then thick and zoned
within. T. Laurocerasi, Berk, in Eng. PL, is, I believe, a
thin, resupinate form of this species. A. cinerea. Sow. t. 388,
f. 3, is, I think, merely Corticium quercinum.
6. S. acerinum, Fr.; crustaceo-adnate, even, smooth, white.
On trunks of living maples. Very common.
37. HYMENOCHiETE, Lèv.
Coriaceous, dry. Hymenium even, beset with short, stiff,
coloured bristles.
1. H. rubiginosa. Lèv.; coriaceous, rigid; pileus effuso-
reflexed, somewhat fasciate, velvety, rust-coloured, then smooth,
bright brown; intermediate stratum tawny-ferruginous ; hymenium
ferruginous.—Sow. t. 26.
On gate-posts, etc. Very common.
2. H. tabaoina, Le«.; coriaceous, then flaccid ; pileus effused,
reflexed, silky, at length smooth, subferruginous ; margin and
intermediate filamentous stratum golden-yellow ; hymenium
paler.
